Click the “Download EvaI”
link to download EvaI or the “How to Install” link to view
installation procedure.

The installation document
only helps you through the process of installing Java and EvaI on a local
computer. When you have downloaded the .zip file you must extract it
to a temporary folder on your local computer before using the
installation guide.

Last time updated is Monday
14th June - 2010

The download below is the latest
version of the Eva Interface it fixes some known
problems in regard to how the user behaves. Primarily, a
update problem with the eva inbred parameter file and a
problem with viewing the largest genetic contributions.

If you want or need to install the
new version of in the "old" Eva Interface folder the you
can directly install the update over older
version of EvaI without doing anything special.

Download and install as described
in the installation document but when the installation program
ask to where to install EvaI browse to the old
installation folder and select this as the new
installation folder. This will automatically replace your current Eva Interface version
with the new version.

PLEASE NOTE:

- Version number not changed within application, read
change history for explanation.

Notes

If for some
reasons your computer doesn’t start the "EvaW.exe"
program try starting the "Eva.jar" program instead. The
reason the "EvaW.exe" may not start is that your
computer have less memory installed than the “EvaW.exe”
program needs. “EvaW.exe” is optimized for speed and
therefore requires more memory than the “Eva.jar”
program.

We recommend a
computer with the following specifications:

2.5 – 3.0
GHz processor or higher.

Memory:

Minimum. 128 Mb of
ram (Depend on population size in data file.).

Recommended. 512 Mb of ram.

At least
15 Mb free disk space.

Even with a
computer of this size, Eva calculation may take minutes
or hours. Depending of how big a population you have in
the data files and how parameters are specified. As an
example we ran Eva on a data file with a population of
24.500 animals on a computer with the above
specifications and it took 20 minutes. You should not
take this general example as a guideline for how long
time the Eva programs need for a calculation, because
the algorithms used in the programs are stochastic
(non-deterministic), which indicate that the complexity
of the calculation is exponentional in the size of the
population size.

Please be aware
that numeric fields should be used with thousand
separators to work correctly. E.g. -1000 should be
written -1.000. The example is using a dot as a thousand
separator (Danish). Which letters you should put as
thousand separator depends on the country and culture
your computer is installed with. You should check that
the parameter values are correct set in the log files in
the runtime dialog.

Future planned
changes

Peer Bergs Eva Version 2.0

Basic changes

Computations of average relationships (based on Meuwissen & Sonesson (1998)

)

EVA
will be less memory consuming due to the implementation
of the algorithm proposed by Colleau (Colleau, J.-J. 2002. An indirect approach to the extensive
calculation of relationship coefficients. Genet.Sel.Evol.
34:409-421) to
compute average relationships

Only changes to the internals
working of the Eva Interface has been done is this version
and a new release of the Peer Bergs Eva program is added to
the Interface. The changes in Peers Eva program are the
following:

Genetic merit of candidates, given in the input data
file, are standardised in order for weights to be
comparable across datasets.

Prediction of rate of inbreeding in output

Version 1.3.07

This version of the
Eva Interface consist mainly of some minor updates to a
number of external files and a revisited general help
document.

Because it is only a
update of external files, we did not have to re-compile the
application. Therefore, you will still see 1.03.06 as
version number stated within the application, but if
you go into "Help->Generel help..." menu the help document
version is update to version 1.7.

Please update your
current installation, to be sure to have a correct
functioning version of the Eva Interface.

Version 1.3.06

This version of
the Eva Interface consist primarily of small bug fixes
which has been annoying and a addition of a
warning not to use the advanced parameters in the Eva
part of the application without knowing exactly how they
influences the computation.

Bugs:

Fixed inbred
contribution lines appeared in the interface
although you have removed them from the computation.

Fixed strange
crash

The interface would sometimes randomly crash for no
immediately reason, because of a parameter error in
the project files. This has been fixed inside the
interface code such that your projects do not need
to get changed.

Fixed advanced
parameter default values

The standard values for the eva advanced parameters has
been update to reflect latest experiences and knowledge.

Removed some
spelling errors from the Interface.

Removed some
internal program documentation form the installation

Additions:

Added warning
to Eva about not using the advanced parameters.

Version 1.3.02
Update 1

It has not been possible to use EvaI in the new Java
1.5 version, due to some broken sorting code in the Java
1.5 version. This has been fixed by implementing a
shuffle/merge sorting algorithm directly. Furthermore, I
have rewritten the whole “Contribution Selection dialog”
to accommodate the directly implemented sorting
algorithm.

Bugs:

Fixed random failure to load mating list
into result view after run.

The failure occurred, because some optional texts
extended the numerical value an integer can hold,
before variable overflow occur. Changed variable from
integer type to long type, which means that the
maximum value now is 2^64. Please do not exceed
this value. If you do exceed the maximum value for a
long EvaI will not show the calculated mating list.

Fixed uppercase ‘E’ letter failure in “eva.dat”
file.

This is actually not an error on the Microsoft
Windows system. But it becomes an error if you move
a project to a Unix/Linux system, because Unix/Linux
systems distinguish between upper and lower case
letters.

Fixed minor error when you click cancel in the
Contribution Selection Dialog.

EvaI would still try to insert selected items even
though you have cancelled the selection. Have
rewritte the logic behind the cancel handling.

Fixed some minor bugs I found doing this update.

Improvements:

I have rewritten “Contribution Selection Dialog”

You can now make multiple selections by pressing
either the shift key or the ctrl key while clicking
the mouse. Sorting is now three ways ascending, descending and
random. You sort the optional text by clicking
either “Available Animals” or “Selected Animals”
headers.Moving of selected optional text is now done by
clicking up and down errors beside the selected
animals list. You select multiple items in the
selected animals list by holding either shift, ctrl
and clicking with the mouse you want to move.

The memory consumption have been lowered
due to the shift to Java 1.5, which mean that you
now can run EvaI on a machine with less than 128 Mb
of ram, but memory requirements still rely heavily
on number of animal in your data file.

Hope you enjoy this update. Please report possible
problems to me as soon as possible.
